The Donaldson-Thomas invariants under blowups and flops

Jianxun Hu, Wei-Ping Li

Using the degeneration formula for Doanldson-Thomas invariants, we proved formulae for blowing up a point and simple flops.

Mukai Flop and Ruan Cohomology

Jianxun Hu, Wanchuan Zhang

Suppose that two compact manifolds $X, X^{'}$ are connected by a sequence of Mukai flops. In this paper, we construct a ring isomorphism between cohomology ring of $X$ and $X^{'}$ . Using…

Gromov-Witten Invariants of Blow-ups Along Points and Curces

Jianxun Hu

In this paper, using the gluing formula of Gromov-Witten invariants under symplectic cutting, due to Li and Ruan, we studied the Gromov-Witten invariants of blow-ups at a smooth po…
